XANES spectra have four or five peaks in the range from 50 to 90 eV, depending on the strength of chemical bonds between lithium ions and donor atoms. Li(1s) XPS spectra also have two or three peaks in the range from 48 to 58 eV. The electron densities on lithium ...

Li(1s) XPS spectra also have two or three peaks in the range from 48 to 58 eV. The electron densities on lithium ions were obtained by DV-Xα molecular orbital calculation (8, 9). The relationship between these spectra and electron states will be discussed. Chemical structures of some ...
